Managed to build all 55 investigators, but I have no idea how to post them... Any help will be welcome.

I did it two ways. I posted photos of them on Flikr next to their player card. And I also recorded what parts I used in a spreadsheet so that others could potentially buy the same ones. The easiest way of course is to just line them up and take some pictures. I always love to see how other people interpret the Investigators into lego!

Hello! I have photos in my phone. How can I move them to PC/ post them from it?

Depends on your phone. Most easily, get a micro USB cable (on many phones, the same cable you use to charge your battery) and use that to connect it to your PC. Then, follow the pop-up window.

Or you could load the forum up on your phone and upload them directly.

Not here. FFG limits each user to something like 10Mb.

People often use a file sharing site and link them in. If you go that route, you can also select a given image, copy its URL, and paste it into a post. That's the norm when people post their paint jobs.

Or upload to BGG. They'll love it over there too.
